Archery bow stabilizer

Abstract

A bow stabilizer that reduces bow shock transmitted to archer's hand includes a plurality of weights disposed about a central shaft. An elastomeric material supports the weights and couples the weights to the central shaft. The central shaft is connected to the frame of the bow. Bow vibration is damped as the central shaft vibrates out of phase with the suspended weights.

The invention claimed is: 
     
       1. An archery bow stabilizer comprising:
 a body member configured for attachment to an archery bow riser, the body member comprising a first groove and a second groove; 
 a first resilient member supported by said body member, a portion of the first resilient member oriented in the first groove; 
 a second resilient member supported by said body member, a portion of the second resilient member oriented in the second groove; and 
 a suspended mass supported by said first resilient member and said second resilient member, said suspended mass surrounding said body member, said suspended mass comprising a different material than said first resilient member. 
 
     
     
       2. The archery bow stabilizer of  claim 1 , said suspended mass comprising a first weight, a second weight and at least one connector attaching said first weight to said second weight, said first resilient member contacting said first weight, said second resilient member contacting said second weight. 
     
     
       3. The archery bow stabilizer of  claim 2 , wherein said first weight and said second weight have the same shape. 
     
     
       4. The archery bow stabilizer of  claim 2 , said first weight and said second weight attached by a plurality of connectors. 
     
     
       5. The archery bow stabilizer of  claim 1 , said body member further comprising a third groove, a spacing between said third groove and said second groove being similar to a spacing between said second groove and said first groove. 
     
     
       6. The archery bow stabilizer of  claim 5 , said stabilizer reconfigurable between first and second orientations, said first resilient member positioned in said first groove and said second resilient member positioned in said second groove in said first orientation, said first resilient member positioned in said second groove and said second resilient member positioned in said third groove in said second orientation, said suspended mass having a first position with respect to the body member in the first orientation and a second position with respect to the body member in the second orientation. 
     
     
       7. The archery bow stabilizer of  claim 1 , said suspended mass comprising a first suspended mass, said stabilizer further comprising at least one secondary resilient member supported by said body member and a second suspended mass supported by said at least one secondary resilient member, said first suspended mass not in contact with said second suspended mass. 
     
     
       8. The archery bow stabilizer of  claim 7 , said first suspended mass having a different weight than said second suspended mass. 
     
     
       9. The archery bow stabilizer of  claim 7 , further comprising a connecting member attached between said first suspended mass and said second suspended mass, said connecting member comprising an elastomeric material. 
     
     
       10. The archery bow stabilizer of  claim 1 , said body member comprising a first body portion and a second body portion, said second body portion moveable with respect to said first body portion between first and second positions. 
     
     
       11. The archery bow stabilizer of  claim 10 , wherein said first body portion is configured for attachment to an archery bow and said second body portion contacts said resilient member. 
     
     
       12. The archery bow stabilizer of  claim 10 , wherein at least a portion of said second body member surrounds said first body member. 
     
     
       13. The archery bow stabilizer of  claim 10 , wherein said second body member comprises a tubular structure. 
     
     
       14. The archery bow stabilizer of  claim 10 , comprising a fastener arranged to fix a position of said second body portion with respect to said first body portion. 
     
     
       15. The archery bow stabilizer of  claim 1 , said body member comprising threaded receptacle. 
     
     
       16. The archery bow stabilizer of  claim 2 , further comprising an auxiliary weight attached to said connector. 
     
     
       17. An archery bow stabilizer comprising:
 a body member configured for attachment to an archery bow riser, the body member comprising an outer surface and an annular groove formed in the outer surface; 
 a resilient member supported by the body member, said resilient member surrounding the body member, said resilient member occupying the annular groove, said resilient member comprising a first material; and 
 a suspended mass supported by the resilient member, said suspended mass comprising a second material different from said first material, the suspended mass surrounding the body member. 
 
     
     
       18. The archery stabilizer of  claim 17 , wherein the suspended mass surrounds the resilient member. 
     
     
       19. An archery bow stabilizer comprising:
 a body member configured for attachment to an archery bow riser; 
 a first resilient member supported by said body member; 
 a second resilient member supported by said body member; and 
 a suspended mass comprising a first weight, a second weight and a connector attaching the first weight to the second weight, the first weight supported by the first resilient member, the first weight surrounding the body member, the second weight supported by the second resilient member, the second weight surrounding the body member, a shape of the connector being different from a shape of the first weight and a shape of the second weight.
